I shoot better with 1911's simply because the triggers are single action and have the feel of a rifle trigger. There is nothing wrong with any of the guns you mentioned, but Kimber seems to be the standard all others are held to. Of course, that comes at a price.

I have been pretty pleased with Springfields loaded line of 1911s. Usually very accurate for the money. I had a loaded operator that was one of the most accurate 1911s I have ever had, customs included.
From the box, I have had two very accurate autos. Both were 45's One a Ruger, the other a Sig 220. I had a Glock 22 that was right on their heels. On Average though I think Sig would get my bet.
